Screen readers play a pivotal role in making computers accessible to blind and visually impaired users. These assistive technologies interpret what is displayed on a computer screen and transform it into auditory or tactile feedback that visually impaired users can understand.
It operates by interacting with the operating system of a computer and the applications running on it. They intercept and interpret what’s being shown on the screen, then read it aloud using a synthesized voice or represent it in Braille on a Braille display.
They can relay everything from text and graphics to menus, dialogue boxes, and even metadata like the names and attributes of control buttons.
Users navigate the computer by listening to the audio output of the screen reader and using keyboard commands to perform actions such as opening apps, reading documents, and browsing the web.
Popular Screen Readers
Different screen readers offer various features and levels of support for applications and web technologies. Some of the most popular screen readers include:
- JAWS (Job Access With Speech): This is one of the most widely used screen readers worldwide. It is feature-rich and offers robust support for web browsing, email, word processing, and more.
- NVDA (NonVisual Desktop Access): NVDA is a free, open-source screen reader that offers many of the same features as JAWS. It’s continually updated by a community of developers, making it a popular choice.
- VoiceOver: This is Apple’s built-in screen reader for its Mac OS and iOS devices. It provides a consistent user experience across all Apple devices, which many users appreciate.
- Narrator: This is a screen reader included with Microsoft Windows. While not as feature-rich as JAWS or NVDA, recent improvements have made it a more viable option for Windows users.
